Unit 11 Solving systems by elimination
Students will understand:
  • Straight lines are widely used to model relationships between two quantitative variables.
  • Patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table.
Students will be able to:
  • Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities.
  • Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.
  • For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.
  • Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.
  • Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects.
  • In a two-way table, use relative frequencies calculated for rows or columns to describe possible association between the two variables.
